This invent-ion relates tov pressing ma.

chines, as garment and laundry pressing mav chinos, and particularly tomachines in which the movable `pressing element vor head is movedpreliminary toward closed position',

andin so doing shifts themotion transmitting parts into motiontransmitting relation, and has for its object connections operable bythe .movement of such motion transmitting parts'or by the movable headto connect the power motor to such connections, when said connectionshave reached effective motion l transmitting relation.

The invention consists in the novel fea-- tures and in the 'combinationsand constructions hereinafter set'forth and claimed.

In describing this invention reference is had tothe accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure l is a side elevation of a pressing machine embodying thisinvention.

Figure 2 is a fragmentary front elevation thereof. w l

Figure 3 is a fragmentary detail view of the handleffor the operating orcontrollingv f mechanism.

This pressing machine comprises, generally, coacting pressing elementsone of.

which is movable toward andfrom the other, actuating mechanism for themovable ele. ment, including an intermittently movable power member,motion transmitting means between the power member and the movableelement, including parts normally arranged out of effective transmittingrelation and movable into such relation by a preliminary movement of thehead or movable element toward closed position, power means as anelectric or other motor, and operating mechanism operable to connect thepower means to said member, and means operated by the motiontransmitting connections for effecting the automatic operation of theoperating mechanism, when the motion transmitting parts g havebeen'brought into effective motion transmitting relation.

I have here shown my mvention as applied to a conventional type ofgarment and laundry pressingmachine, including a stationary pressingelement or buck 1, and a mov- `able element or head 2, movable towardand from the buck 1. The buck 1 is mounted upon a suitable bracket 3,which in turn is lever or yoke 6, pivoted between its ends at 7, to astandard '8, rising'from the frame of the machine or the rear leg 5thereof, the rear arm of the lever carrying a suitable weight/9 forcounter-balancing the head, for

moving it toward open position. Also a spring 10 is usually connected tothel rear arm o f the lever 6 to act in conjunction with the weight 9.

The intermittently actuated power member is here shown as .a lever 11,pivoted at 12 between 'its ends to the lower end ofthe leg 5, this`lever being actuated by an intermittently rotatable shaft 13 having aneccentric 14 thereon, lcoacting with 'a face 15 on the front end of thelever 11. The shaft 13 makes a half revolution during each operation andis actuated by the power means, which is usually an electric motor 16.-'Th1s motor is preferably constantly running, instead of an alternatelystarting and stopping, and the motion is transmitted to the shaft 11-through mechanism housed within the casing 17 and including avperiodicor half revolution clutch of an suitable construction. As theconstruction. thusfar described, forms no part of this invention,further description is lthought to be unnecessa it being merelynecessary to bear in min that the periodic clutch is thrown to its inposition manuallyor by a manual operation, and automativ cally thrown toits out position after the shaft 13 has completed each half revolution.

The lever 11 is caused to follow the cam a suitable s ring 18.

- The motion transmitting means between vthe lever 11 and the head 2, inadditionv to the yoke or lever 6, comprises toggle links 19 and 20,pivoted together at 21, and pivoted respectively at'22 and 12'to therear arm of the yoke or lever 6, and to the frame, the link 2O beingusually pivoted to the frame on the same pivot-12 that the lever 11 ismounted on. In, vaddition to this toggle which. when straightenedapplies pressure to the head 2, the motion transmitting means includes aconnection for straightening the toggle and causing it to ap ly thepressure. This connection is here s own as a thrust link 23 pivoted at24 to the rear arm of the lever 11,'and

normally arranged in nearly upright posibyV ion

tion, it being held in such position by a nut 25 threading on a screw26, which nut 1s pi-voted at 27 to the rear leg `5. A spring 28 isinserted between the frame and the link 23 and tends to thrust the linkagainst the nut 25. This thrust link 23 coacts with an extension 29 ofthe link 19, the thrust link 23 and the extension 29 being provided withcoacting teeth 30 and 3l.

When the press is open and the toggle links 19, 2O are foldedrearwardly, the tooth 31 is located to the rear of the tooth 3() of thethrust 23, but when the head 2 is moved preliminarily toward closedposition by pulling down the handle 32, thetoggle links 19, 20`are movedto such a position that the teeth 31 and 30 come into engagement, andhence, any downward movement. of the power lever 11 is transferredthrough the thrust link 23 to the toggle and causes the toggle to movemore nearly into a straightened position and applies pressure to thepress head. The

parts are preferably'adjusted, so that, the

teeth 31 and 30 do not come into engagement until after the press head 2has been preliminarily closed or until the press head 2 is so closetothe work on the buck l, that it is impossible for the operator to havehis hands or fingers between the buck 1 and the head 2, or if he doeshave his hands in this position, the head cannot be closed far enough tobring the tooth 31 into engagement with the tooth 30.

The operation mechanism for throwing the clutch to connect the motor 16to the shaft 13 comprises a rock shaft 32* extending forwardly andrearwardly of the machine on the right hand side thereof and having arock arm 34 thereon and also a handle 35 at its front end. The rock arm34 coacts with the rock arm 36 mounted on a rock shaft 37in the clutchhousing 17. The rock shaft 37 serves to throw the clutch to its inposition. As here shown the rock arm 34 is shifted to actuate the arm 36and is provided with a pawl 38 pivoted at 39 and coactmg with the` tooth40 on the armv36. The arrangement of the pawl 38 and tooth 40 is suchthat depreion vof the handle rocks the shaft 32* and arm 34 in a counterclockwise direction, causing the pawl 38 during sucn movement of the'arm 34, to press against the tooth 40 and rock the lever 36. in aclockwise direction, until the pawl clears the tooth 40.

-When the operator releases his hold onthe handle the weight of the4 arm34 returns the handle to its normal position and the pawl 38 i ratchetsto the front left hand side of the tooth 40. Suitable set screws 41 and42 are provided for adjusting the relative positions of the pawl 38 andtooth 40. The construction of this'operating mechanism forms no part ofthis invention. j

The connection between the motlon transmtting means operated by thelever 11 and the operating mechanism of the shaft 32l and associatedparts, by which said operating mechanism is automatically actuated whenpreliminary closing movement'of the head 2,

and actuate the latch to cause it to actuate thejshaft 32a, and hence,thrust the clutch 43 designates the arm, which is here shown as xed tothe toggle link 20 to move therewith, this arm extending forwardly andtogether with the link 20 forming a bell crank.

44 designates the latch depending from a rock arm 45 extending inwardlyto the left from therock shaft 32a, the latch being pivoted at 46 tosaid rock arm 45. The latch is formed near its lower end with a tooth 47and also with an inclined face 4S below the tooth, this inclined face 48coacting with a fixed part at 49. During the downward movement of thelatch, such coaction causes the latch to be moved on its pivot againstthe action of a spring 50 to the right, and causes the latch todisengage itself from a member 51 which coacts therewith. This member 51is here shown as a lever pivoted at 52 and connected by a link 53 to thefront end of the arm 43 it being connected to the arm 43 by a lostmotion connection, as a pin and slot connection- 54.V The engagingprojecting end 55 of this lever 51 also coacts with inclined facedownward movement of this latch 44 rocks the shaft 32* of the clutchoperating mechanism and causes the clutch to be thrown to its inposition, so that the shaft 13 makes a half revolution from` theposition diametri-l cally opposite that shown in- Figure `1, anddepresses the lever 11. V.As the thrust link 23 and the extension 29 ofthe toggle 19 are 1n -motion transmitting relation the actuation of Atheower lever 11 1s transferred to the head e downward movement'of thepower lever 11 actuates the thrust link 23 and causes the toggle links419 and 20 to` move more nearly into their dead center line, or into theposition shown in Fig. 1. vAfter thearm 43 leased from the lever 51, sothat, the handle and shaft 32a are free to return to their normalposition for manual opera-tion to open th'epress. When the latch 44moves upwardly to its normal position the latch face 48 is brought intoengagement with the end 55 of the lever 51, as shown in Fig. 2.

During the manual operation of the shaft 32 to open the press the latch44 is depressed and hence moves relatively to the member 51,.

and during its downward movement the tooth 47 ratchets-into engagementwith the member 5 1, the member 51 with its engagingor projecting end 55having, during the opening movement of the press, been raised intoposition to engage the shoulder 47 of the latch 44 by the lever 43, sothat the spring acting on the'latch 44 moves the latch into engagementwith the tooth 55 of. the lever 51and the parts are in position for thenext operation.
